An art exhibit made using 1,500 used plastic bottles was completed Sept. 4 along a Waller Creek pedestrian bridge.

Approximately 800 flowers made using recycled material now line both sides of the pedestrian bridge behind the Waller Creek Plaza, according to the city. The project, part of the "Let's Can It! Austin" campaign, encourages Austin residents to respect the city's environment.

The city's Watershed Protection Department and SafePlace Expect Respect program staff combined to host eight flower-making workshops around Austin, transforming used plastic bottles into flower-shaped designs. The full exhibit, completed Sept. 4, will be on display through November, according to the city.

Volunteers and city staff remove about 250 tons of trash from Lady Bird Lake each year, with much of the debris dumping into the lake from streets, parking lots, sidewalks and parks, according to a city statement. For more information about reducing litter's impact, visit
